Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595086, here are decompositions:

23 + 31595063 = 31595086
167 + 31594919 = 31595086
179 + 31594907 = 31595086
317 + 31594769 = 31595086
359 + 31594727 = 31595086
503 + 31594583 = 31595086
839 + 31594247 = 31595086
953 + 31594133 = 31595086

Showing the first eight; more decompositions exist.
